The Nicholas School of the Environment is hosting the Flat Grok Video Contest. We are on an unsustainable course. While world populations and consumption grow, resources diminish and global warming threatens our way of life. In his blog The Green Grok, Dr. Bill Chameides, dean of the Nicholas School of the Environment at Duke University, elucidates … Read More “Grok my Flock” »

State of the Field: Shark Conservation Policies

March 1, 2011March 1, 2011 David Shiffman 6 Comments

Conservation, Science

Shark populations around the world are crashing. Researchers have reported that many populations have decreased by 90% or more since the 1970’s. The leading causes for these precipitous declines are bycatch, which kills tens of millions of sharks each year, and the shark fin fishery, which kills as many as 73 million sharks each year. In this edition of State of the Field, I will explain what different countries are doing about this problem.

In many parts of the world, it is still legal to cut the fins off of a still-living shark and dump the rest of the animal overboard where it will bleed to death or drown. Other nations have a variety of management policies.

The Nicholas School of the Environment is seeking scholarly editorial contributions to Environmental Leadership, a 2-volume, 100-chapter reference handbook that is part of the new SAGE Reference Series on Leadership. Chapters are anticipated to be 7000 words. This is a unique opportunity to help define environmental leadership. Academic and public libraries will be able to purchase the handbook as both a printed and a digital product.

The high density of sea turtles at the Archie Carr National Wildlife Refuge provides a wonderful opportunity for research, and a team from the University of Central Florida takes full advantage of it. They were kind enough to allow me to tag along.

Terrible Terminal Groins

ft macon — check out the sand loss on Ft. Macon, which has a historic terminal groin, www.sierraclubnc.blogspot.com

Tomorrow a bill will be introduced into the NC House that allows the use of terminal groins to protect private property along the coast, overturning the 1979 ban on hardened structures along the coast. Although NC would join all of the other eastern seaboard states in allowing such protections, the bill, if passed, would also end a long history of attempting to maintain a natural coastline. This natural coastline is why the Outer Banks have become such a popular tourist destination, bringing millions into the state economy each year.

So why might North Carolina leaders turn their back on historical decisions? This year’s General Assembly is under a new majority – for the first time since 1898, led by Republicans. Rising populations along the coast are using this as an opportunity to demand more permanent solutions to shoreline erosion. Previous strategies of beach restoration, inlet channel realignment, and sandbagging are no longer adequate to coastal property owners. However, though terminal groins may seem like an easy solution, they are not as simple as they seem at first glance. It’s these nuances that make them a really bad idea, both for maritime ecology we’ve worked so hard to protect and for the wallets of North Carolinian taxpayers.

From the Guardian: Japan has temporarily suspended its annual whale hunt in the Antarctic after anti-whaling activists obstructed its fleet’s mother ship. Officials in Tokyo have conceded that this year’s mission, which had again been the target of international criticism, had not gone as well as hoped and the fleet may be called home early, … Read More “Japan temporarily suspends Antarctic whale hunt” »

State of the Field: Is catch-and-release fishing harmful to sharks?

February 8, 2011February 2, 2011 David Shiffman 10 Comments

Conservation, Science

In the wake of the new Marianas Islands shark conservation law, a debate has been raging on the shark listservs. The law wouldn’t have been possible without support from several local recreational fishermen- people who often take tourists catch-and-release fishing for sharks.

“When I heard of your effort in Hawaii to ban the sale,trade and possession of shark fins I knew if the CNMI was to follow someone with inside connections to the fishing world there had to espouse it and grow it. They do not like being told what to do from outsiders. I was not an outsider, and I fished alongside two of the very top level fishermen who happened to be upper level politicians whom I respected. Rep. Diego Benevente was one of them. I spoke with him and asked him to introduce a bill which replicated Hawaii’s law, and he did so. I kept constant contact with him and his staff in the effort to see this bill become law.”- Captain William McCue

Many shark conservationists support catch-and-release fishing, claiming that it allows fishermen the thrill of catching a large animal without killing it. Captain McCue reports that in the last 20 years:

“I’ve caught over 300 sharks in the that time a killed four- and if you include spiny dogfish it’s caught well over 2000 sharks and still killed only four- two of which were promptly eaten.”

However, some (such as “My Sunset Rendezvous” author Ila France Porcher) claim that even when a shark is released, the stress from being caught often still causes long-term damage or even death.

“As a shark ethologist, I have personally witnessed sharks who were hooked and fought, and who broke the line, emerge from the ordeal with a jaw so damaged that they lost weight and died over the following weeks or months. A high fraction of sharks caught suffered this fate, and they suffered greatly as a result of this enjoyable passtime pursued by sports fishermen. It would be great news to hear that you switched from a blood sport to a sport that celebrates the life that still remains in our seas, such as diving and photography.” – Ila France Porcher
